Bob Tillotson knew the avalanche danger was high when he set out with friends into the Utah backcountry on his snowmobile. But he also knew which areas to avoid. Or so he thought. On January 13, 2024, an avalanche hit Bob without warning, carrying him down the mountain in a wave of snow. When he stopped, he was completely buried and separated from his group.Dustin Sweeten was snowmobiling with a separate crew that day. Just before he was ready to head home, he saw what looked like an avalanche in the distance and went to go check it out. When he got there, he saw two people from Bob’s group. They told him their friend was buried. Then they saw a glove poking out of the snow. We also speak with Sandra Riches, the executive director of British Columbia AdventureSmart, about outdoor winter safety and what to do if you or someone you’re with is in an avalanche.Visit onstar.com/features/crisis-help to learn more about how OnStar can help Members in a moment of crisis.Video credit: Ammon Sweeten / YouTube @MountainWolf-ut.
